内容説明
Optical dating is a rapidly developing technique, used primarily in the dating of sediments deposited in the last 500,000 or more years. As such increasing numbers of Quaternary geologists, physical geographers, archaeologists, and anthropologists are now relying on the results produced. Written by one of the foremost experts on optical dating, this book aims to bring together in a coherent whole the various strands of research that are ongoing in the area. It gives
beginners an introduction to the technique as well as acting as a valuable source of up to date references. The text is divided into three parts; main text, technical notes and appendices. In this way the main text is accessible by those researchers with a limited knowledge of physics, with the
technical notes providing depth of understanding for those who require it. The first part of the book is concerned with basic notions and an introduction to the standard techniques, as well as several illustrative case histories. It goes on to then discuss the limitations of the technique and factors affecting reliability.
